A time ago I posted a few messages/questions about magnifiers.
Now the magnifier is already build.It looks very cool and Iīve designed
it with magsim,inca,optmag and mandk.
The driver has a diameter of 31,7" and is 40" high.
There are around 250turns of 12gauge. The last 15 turns are spaced.
The driver construction was very difficult,because the wooden varnished main frame.(there are no nails,screws;only wooden sticks and wood glue)
The turns lay on a frame,consists of 22 (1,18" wide) arcrylic rods.
The complete driver is packed in three layers (each 0,0315")clear PET (mylar?) plastics.Iīve made a isolation test with this plastic,and I couldnīt see those carbon tracks like Bert Pool.
The primary is a flat coil with 2,36" wide copper ribbon.
Distance prim.sec is only 0,4-0,5" because the wanted highest coupling.
A coupling test at lowest prim. position gives k12=0,41
The teritary has a diameter of 12" and has a turn length of 62" (1075turns)
main toroid 59"x12,2"
lower toroid 29"x6,7"
Iīve made a few low power tests with
around 3-4kVA and 10kV with static gap.
Around 16" stremers from breakoutpoint C3 and than
racing sparks on L2 from top turns to the lowest turns.
I called they racing sparks,but i donīt know what it is.
They arenīt very bright.
Iīve than arced the transmissionline to a grounded metal rod.
If I have a distance to the rod less than 8" the racing sparks
disappear.And the transmissionline arecd to ground.
The problem is the daylight,so i couldīnt see where they comes from.
They donīt arc to the primary,but between turns and plastic downwards,
one time upwardsfrom the lower turns to the middle.
Iīve made photos which I can post you,but because the daylight you couldnīt see a spark/streamer.
Iīve a photo postet to a coiler,which has uploaded it to his internet site.
The sphere on this photo is only for measurements and is now displaced
(now 33"x5" toroid)
